The Observational Scale of Level of Arousal: A brief tool for assessing and monitoring level of arousal in patients with delirium outside the ICU

Abstract: Altered level of arousal, encompassing drowsiness and hypervigilance, affects at least 10% of acutely unwell patients. Existing scales provide limited coverage of milder changes in level of arousal. We devised the Observational Scale of Level of Arousal (OSLA) to enable more detailed arousal assessment. Here, we provide a preliminary case-control study of performance of the OSLA in assessing abnormal level of arousal associated with delirium outside the ICU. Methods: Hip fracture patients (N = 108, median age … Show more

“…Demographic information was collected and Clinical Frailty Scale (CFS) completed 18 . Delirium severity was measured by the Memorial Delirium Assessment Scale (MDAS) 6 and levels of arousal were assessed using the Observational Scale of Level of Arousal (OSLA) 19 and Modified Richmond Agitation and Sedation Score (m‐RASS) 20 . PD motor severity was assessed using the Movement Disorder Society Unified Parkinson's Disease Rating Scale Part III (MDS‐UPDRS III) 21 .…”

“…The delirium screening was supported by cognitive testing adjusted to patients' normal cognitive function, a formal test of attention, and the Observational Scale of Level of Arousal (OSLA). 9 The delirium screening was repeated on day 1 (contact with physician), day 2, day 4, and day 6. If a patient had symptoms of delirium on day 6, the delirium screening was repeated once a week until symptoms resolved.…”
